DAVID LEMOINE AND GEORGE I. FOURNIER, OF :VHITINSVILLE, MASSACHUSETTS;

SPINDLE BEARING;

Application filed October 12, 1922. Serial No. 594,169.

To all whom it may concern:

Be it known that we, DAVID LnnoINE and Greece P. FoURNmn, citizens of the United States, both residing at VVhitinsville, in the county of Worcester and State of Massachusetts, have invented a new and useful Spindle Bearing, of which the following is a specification.

This invention relates to a spindle bearing for a twisting or spinning frame.

The principal objects of the invention are to provide an improved construction of cylinder and oiling arrangement whereby the cylinder can be made of harder material than has been the case heretofore, so that its bearing surface will last longer and whereby the cost of construction will be reduced; and to provide certain improvements in the oiling of the bearing surfaces.

Reference is to had to the accompanying drawings in which- Fig. 1 is a central diametrical section View of a spinning spindle and bearing parts constructed in accordance with this invention;

Fig. 2 is a side view of the bolster; and

Fig. 3 is a plan of the bolster.

In the manufacture of the cylinder as heretofore constructed it was formed of cast iron because of the projecting portion 11, which contains the oil passage and which is necessarily eccentric and constitutes a material projection from the center of the device. This necessitated the manufacture of the whole cylinder 10 of this material and limited the hardness and bearing qualities thereof.

It is a feature of this invention that the cylinder itself is separate from the surrounding collar 12 on which the projection 11 is mounted, and the parts 11 and 12 are made of cast steel as before while the cylinder 10 is made of cold rolled steel. This cylinder is formed up in well known mechanical ways from the cold rolled stock and turned with a cylindrical surface at 15, and an integral collar at 16. It is of course bored out inside in the usual way and is provided with an oil passage 17.

The collar 12 with the projection 11 thereon of the usual form, is formed of any desired metal, preferably cast steel, and bored through to such a size that the cylindrical part 15 can be forced into it with a driving fit to constitute preferably the only means of holding these two parts together."

The oil passage 17 then registers with an oil passage in the projection 11 of the usual kind. When so assembled these parts are of the same size, shape and appearance out side as is usually the case, screw-threads being provided on the cylinder for the usual nut 18 for holding the parts on the spinning frame.

Inside the bore of the cylinder 10 is placed a bolster 14 for receiving the bottom of the spinning spindle 13. This bolster is provided with a bottom conical bearing 20, and with two cylindrical bearings 21 and 22, one at the top and the other near the bottom having a diameter for fitting the interior of the cylinder. There is a reduced cylindrical surface 23 between them for retaining oil either with or without a wick or the like. Through the whole length of the part of the bolster embodying the portions 21, 22 and 23 are two opposite longitudinal grooves 24 for feeding the oil down into the conical bearing surface below. Also there are transverse oil passages 25 through the surfaces 23 and 24 arranged to avoid registration with the grooves 24:.

The bearing surface 22 is provided with the usual key 26 fitting into the groove in the cylinder to prevent rotation of the bolster. The spindle 13 is provided with the usual pulley 30 and is operated in the usual way.

It will be seen that the manufacture and assemblage of this device is very simple, involving a reduction in cost ordinarily when they are made in large numbers, and permitting of the manufacture of the bolster casing itself of harder material than has been the case heretofore; also the bolster is provided with an improved lubricating system for the bearing surfaces.

Although we have illustrated and described only a single form of the invention we are aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.

Therefore we do not wish to be limited to all the details of construction herein shown and described, but what we do claim 1. As an article of manufacture, a spinning spindle bearing cylinder consisting of a cold rolled steel tubular part closed at the bottom and open at the top, having an integral collar near the top, and provided with a space therein for receiving a bolster and the bottom or the spindle and a collar therefor of cast steel, fitting on the cylinder just under the first named collar with a driving fit and provided with a projection thereon at one side having a passage communicating with the interior of the cylinder for deliver" ing oil thereto.

2. As an article of manufacture, a bolster for a spinning spindle cylinder having two cylindrical surfaces, one spaced from the bottom and the other located at the upper end of the bolster, a surface with a reduccd portion between the two cylindrical surfaces, two opposite parallel vertical grooves throughout the length of the bolster between said cylindrical bearing surfaces for conducting oil from the top of the holster to the bottom, and passages extending therethrough for conducting oil located out of registration with said grooves.

In testimony whereof we have hereunto aflixcd our signatures.
